the move up from 100 NL to 200 NL wasnt too bad for me. Play is definitely better, more aggressive and less complete tards. However, there are still enough players who limp with Q10o UTG and call raises. The toughest part for me was handling the swings of money as a poor college kid a couple buy-ins at 200 nl make a difference. The way i got past the transition was playing 4 tables of 100 NL and 2 tables of 200 NL. After i became comfortable i went 2 of 100 and 4 of 200 and then finally all 6 at 200. GL in your transition.
